According to d'Avity, Fra Gilbert d'Assailly or de Sailly, was of
excellent and kindly disposition, but inclined to prodigality,
especially where the military was concerned, to the point that he borrowed excessively. Having exhausted
the Order's entire treasury, he was compelled to take on a loan on
the condition that he captured Pelusium [a town in Egypt] for the Order,
by beating the infidel. This was successfully carried out
on 3 November 1168.1

That year he held a Chapter General in Jerusalem; when he
realised that
the Order owed over 100,000 gold pieces, the enormity
of the debt filled him with loathing and, heartbroken that his plans were not passed, he
abdicated from the office of Grandmaster in
1169.1

To be fair to d'Assailly, Saladin was at the start of his great onslaught on
the Holy Land which was to culminate in the fall of Jerusalem itself within
the next 20 years. According to Seward, the costly and disastrous outcome
of the campaign against Saladin, almost bankrupted the Order with the result
that d'Assailly suffered a nervous breakdown in 1170, abdicated and became
a hermit. He later drowned crossing the English
Channel.2
